Journal of Pedagogical Research, 9(5), 98-120. https://doi.org/10.33902/JPR.2025356012602-3717https://hdl.handle.net/10272/27661The purpose of the research was to detect elements of specialised knowledge of an experimental sciences teacher in the design and implementation of a field trip in Secondary Education in order to draw pedagogical implications in initial teacher training. We developed a case study of a science teacher who carried out an educational intervention about heritage through a field trip. An interview and the field book design were used as instruments for data collection. Data were analysed using content analysis guided by a theoretical and methodological model of the specialized knowledge of teachers who teach experimental sciences, mathematics and social sciences. The results showed that the teacher has in-depth Content Knowledge, which allows him to characterise the river, an ecosystem and research in a heritage environment, as well as Pedagogical Content Knowledge using specific resources, methodological strategies and activities to teach science in Secondary Education. From these results, a series of implications have been drawn, such as the importance of an in-depth content knowledge related to topics to be taught and an interdisciplinary teacher training.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Case studyField tripHeritageScienceTeacher knowledgejournal article10.33902/JPR.202535601open access
